蓝宝石光纤温度传感器K值标定系统

         

摘要

标定了一种镀制氧化锆陶瓷薄膜的蓝宝石光纤黑体腔温度传感器.标定系统用氢氧焰枪作为热源,以Modline3红外测温仪作为标准传感器,采用数据采集卡(PCI20612)对被校准传感器和Modline3的输出信号同步采集,通过比较法得到K值.实验验证了该方案的可行性,测得K值为98.578×106(V·m2/W),并得到该传感器温度-电压曲线,系统简单,方便,具有一定实用价值.%A kind of sapphire fiber blackbody cavity temperature sensor which was sprayed by ZrO2 film was calibrated. In this measruement system, hydrogen-oxygen gas flame welding machine was used as heat, Modline 3 infrared themometer was the standard sensor,data acquisition card(PCI20612) collected both of output of the calibrated sensor and Modline3. K was obstained by comparison. Experiments demonstrate the feasibility of this program,the results show K is 98. 578 x 10 ( V · m /W) ,and the T-V curve is presented. The calibration system is convenience and practical.
